This invention appertains to new and useful Improvements in means forsterilizing and drying brushes to the extent required by law in someStates.

The principal object of the invention is to provide a combinationsterilizer and drier which in operation will result in a thoroughsterilization of the brush and subsequent drying thereof so that verylittle time is consumed between customers in treating and drying thebrush.

Other important objects of the invention are to provide an apparatuswhich is of simple construction, of low cost to manufacture and a devicewhich will not be susceptible to the ready development of defects.

These and various other important objects and advantages of theinvention will become apparent to the reader of the followingspecification.

In the drawings- Figure 1 represents a side elevational view of theapparatus.

Figure 2 is a rear elevational view.

Figure 3 is a fragmentary vertical sectional view taken substantially onthe line 33 of Figure 1.

Figure 4 is a fragmentary detailed sectional view taken substantially onthe line 4-4 of Figure 3.

Figure 5 is a fragmentary detailed sectional view showing the switch.

Figure 6 is a sectional view taken substantially on the line 56 ofFigure 1.

Figure 7 is a diagrammatic view showing the electrical connections withthe switch.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 represents the base which has the recess 6therein for accommodating the lower portion of the sterilizing fluidcontaining bowl "I. Numeral 8 represents a post rising from one end ofthe base 5 and provided with the reduced upper end portion 9 which fitsinto the bifurcated lower end portion IU of the swingable arm II. A pinl2 extends through the bifurcated portion Ill and through the reducedportion 9 of the post 8 for swingably connecting the arm II to the post8.

Numeral I3 represents a small electric motor which is secured by thesplit clamp hi to the upper end of the arm I I, the clamp being formedwith ear portions l5 and a bolt [6 extends through these ear portionsfor securing the clamp to the arm II and in clamped relation with themotor [3.

An elongated centrally bowed stack I! of transparent material is securedto the bottom side of the motor [3 by the split clamp band I8. Thisstack I1 is of such length as to depend into the bowl 1 and below thesurface of the sterilizing fluid therein.

The armature shaft [3a of the motor l3 extends downwardly into the stackl1 and carries the block l9 from which depends a plurality of springarms 20 each having an inwardly curved end portion 2! which fits underthe head portion 22 of the brush 23, which brush can, of course, beespecially constructed to accommodate this form of clip or in someinstances a clip can be modified to accommodate conventional types ofbrush handles. From the brush handle 23 of course extends the brushbristles 24.

When the arm H is swung downwardly so that the stack [1 depends into thebowl 1, the brush will be immersed in the sterilizing fluid.

Numeral 25 generally refers to the automatic switch which closes thecircuit with the battery 26 when the arm II is lowered to start thebrush rotating in the sterilizing fluid.

As shown in Figure 5, the switch consists of an arm 21 extendinglaterally from the arm II and this is connected by the pivotal link 28to the contact blade 29 of the switch, which is in wiping engagementwith the contact finger 30 stationarily fixed.

A case 3| is secured to the post 8 and has an opening 32 in its top sidethrough which the link 29 operates.

Obviously when the arm I l is swung backwardly the switch is broken andthe motor is deenergized. However, when the arm is swung downwardly tothe position shown in Figure 1, the motor is operated by the closing ofthe switch and the brush head operates in the sterilizing fluid, orwithout the sterilizing fluid, as when the'bowl is removed and theoperation is to dry the brush.

It is to be understood that artificial means for drying the brush can beemployed such as a fan driven by the motor which, of course, willaccelerate the drying of the brush and materially reduce the interval oftime necessary in accomplishing this result.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A sterilizing apparatus of the character described comprising a basehaving a depression therein, a post rising from the base, anarcuateshaped arm pivotally secured at one end to the upper end of thepost and adapted to abut the post when swung to a position to support abrush over the base, a motor secured to the free end of the arm andincluding an armature shaft, 2. spring clip holder for holding a brushin depending position, a transparent stack depending from the motor andadapted to depend over the base, a bowl adapted to seat in thedepression and to receive the stack when the arm is disposed over thebase, said arm being adapted to be swung laterally to permit removal ofthe brush from the holder.
